    • If “AC Three Phase” is selected, an additional drop-down menu will appear for selecting the voltage type.
  2. Select the Voltage Type (for AC Three Phase only):
    • If you selected “AC Three Phase”, you need to specify the type of voltage measurement:
      • Line to Line Voltage: Voltage measured between two lines.
      • Line to Neutral Voltage: Voltage measured between one line and the neutral point.
  3. Enter the Voltage (V):
    • Find the input field labeled “Voltage (V)”.
    • Enter the voltage value of your circuit in volts (V).
    • Ensure the value is numeric and accurate.
  4. Enter the Current (A):
    • Find the input field labeled “Current (A)”.
    • Enter the current value of your circuit in amperes (A).
    • Ensure the value is numeric and accurate.
  5. Calculate the kVA:
    • Click the “Calculate” button to perform the conversion.
    • The calculator will use the entered values and the selected options to compute the apparent power in kVA.
    • The result will be displayed in a box below the button.
    • The result is formatted to three decimal places for precision.
  6. View the Result:

Formulas used for Amps to kVA Conversion

Explanation of the Formulas

  1. Single Phase AC Circuit:
    • In a single-phase circuit, the power (in kVA) is simply the product of the voltage and current, divided by 1000 to convert from VA to kVA.
  2. Three-Phase AC Circuit (Line to Line Voltage):
    • In a three-phase system with line-to-line voltage, the power is calculated by multiplying the voltage and current, and then multiplying by the square root of √3 (approx 1.7323​≈1.732). This accounts for the phase difference in a three-phase system. The result is then divided by 1000 to convert from VA to kVA.
  3. Three-Phase AC Circuit (Line to Neutral Voltage):
    • In a three-phase system with line-to-neutral voltage, the power is calculated by multiplying the voltage and current, and then multiplying by 3. This is because each phase carries part of the total power. The result is then divided by 1000 to convert from VA to kVA.
